A ire- A retaining notch 22 `is formed inthe back ofthemagazine 18 to receive the nose 24` of 70 a `retaininglever `23 pivotallymounted in` the lhandle., In `the construction hereinshown this "lever is pivoted intermediateits ends, its lower end `havingan olf-set finger 25 that rests against theside of an actuating 75plunger 26. i This plunger is mounted in a well in the side part'of thehandle 10, and is seated upon a spring 27 'in the bottom of the well,which spring normally forces the plungerlupwardly. A retaining leveroperating cani 28 formed on the side ofthe plunger 26 operatesagainstthe finger 25 on the retaining lever 23,`andwthe upper end' ofthe plunger engages Va recess in the1breech bolt under certainconditions, to be herein-lV after explained, and holds the breech-boltin its backwardpositioingas shown herein" a v prong 29 `being formed onthe end ofthe plunger t'o engage'the breech-bolt at the proper timenJ tThe lever23 is forced toward theQ magazine by a spring plunger 30`seated onQa spring 31 located in arecess in the sear 17. It lwill benoted that this arrangement of parts enablesa single spring to perform95 the double function of" forcing the sear 17 into positionV toengagethe notches in the hammer 16 and also of forcing the lever23 to'engagethe' notch in the edge ofthe maga` ziner.` A
